Abstract
The crystal structure of double complex salt [Pt(NH3)5Cl][ReCl6]Cl×H2O is determined. Crystallographic characteristics are: a = 23.9502(4) Å, b = 7.5963(1) Å, c = 8.9016(2) Å, V = 1619.49(5) Å3, space group Pnma, Z = 4, dx = 3.150 g/cm3. The packing of structural fragments is studied. It is shown that on heating the salt in a helium atmosphere up to 840 °С a mixture of two solid solutions of fcc Pt0.90Re0.10 and hcp Pt0.25Re0.75 forms.
